Application filed December 18, 1911. Serial No. 866,149.

To all whom it may concern Be it known that I, HENRY L. \Vmsrow, acitizen of the United States, rcsiding at l" River, in the county ofBristol and State ot 5 Massachusetts, have invented new and usefulImprovements in Pails, of which the following is a specification.

The invention relates to pails, more par-- ticularly to dinner pails andhas for an object to provide a dinner pail forcontaining various,articles of food and in which an eventemperature of the food can beapproximately maintained. For the purpose mentioned, use is made of aseries of receptacles, one adapted 'to fit within the other with thebottom of one receptacle consti tilting the cover of an adjacentreceptacle, the outer receptacle being provided with walls having thespace between the same filled with a material that is non-condiuativeinglmy device from one place to another.

eference is to be had to the accompany ing drawings constituting a partet this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is avertical'sectional view of my device. Fig.2 is a horizontal sectionalview taken on the/line 22 in Fig. 1, looking in the direction ofthearrow.

Referring more particularly to the views, I provide a receptacle 10having walls 11 and 12, the said walls being spaced apart 'with anon-conductive material 13, such as asbestos or the like, interposedbetween the a -wa1ls 11 and 12. A bottom 14 is provided for thereceptacle 10 and consists of walls 15, 16, the said walls being spacedapart to receive therebetween a non-conducting material 17,similar tothe non-conducting ma- 15 teir'ial 13, the saidloottom 14 being solderedor other-wise conveniently secured to the ,lower end of the inner-wall12 to provide a 'chamber1 8,; 1

Areceptacle 191 s provided with an upper so flanged end 20 and a bottom21 and the said receptacle 19 is adapted to fit within the receptacle 10with the flanged portion 20 resting upon the upper end of the receptacle10- so that the bottom 21 01? the receptacle 19 loo-will form acover-for the chamber 18, suithandles,22 are secured to the upperflanged end 20 of the reccptarlh 15), the said handles being arranged tolie within the plane of the outer wall 11 ot the receptacle 10 for apurpose that will be hereinafter more fully disclosed. A thirdreceptacle ,23, provid d with a Hanged portion 2i and a. boltmn 25,consisting ot sparcd walls 263 and 27 ha ring a l1UI1-(HHl1l(!llV6llltllul'lzll 2S, sii'nilar to the non-comluctivc materials13 and IT, interposed betwe n the walls 26 and 27, is adapted to bereceived within the reccptacle 15) so that the bottom 25 of the receplaclc will form a cover for the chamber 25) formed by the walls andbottom 21 oi. the remiptacle 19, as shown. in Fig". 'l, the flangedportion 2 01 the receptacle 23 being adapted to repose upon the flangedportion 20 of the receptacle ll) with the upper extremity of thereceptacle 23 extending upwardly beyond the upper end of the receptacle19.

Secured to the outer wall 11. ot' the receptacle 10 are knobs 3011a vingpirotally connected thereto the ends of a bail. 31 and mounted toinclose the upper end oi the reccptacle 10 is a cover 32, provided witha handle 33 and a dependingperipheral flange 34:, the lower end of whichis adapted to abut agar-inst the knobs 30, thus limiting the downwardmovement of the cover, the mentioned knobs so being :ulaptrafl to act asstop members for the cover as will be readily understood. 15y referringto Fig. 1, it will be seen that the cover 32 not only acts as a coverfor a chamber 35, formed by the walls and bottom of the receptacle 23,but also iucloses the upper end of the receptacle 10, the upperextremity of the receptacle 1O beingadapted to engage the under side ofthe cover, thus sealing the chamber 35.

The chan'iber '18 is adapted to receive a warm liquid and by providingthe nonoonductive material between the walls of the receptacle L0 andbetween the walls of the bottom thereof, the heat contained in theliquid will be prevented from radiating out" wardly through the walls ofthe receptacle. In a similar manner the heat contained in any foodWithin the chamber 29 will also be prevented from radiating outwardlythrough the walls of the receptacle ll) inasmuch as the wallso'l thereceptacle 10 act as a backing for the walls of the rcceptmrle .19, thewalls of the receptacle 10 being spaced apart and having interposedlhcrc
